We developed a composite (ABC) consisting of alumina bead powder as an inorganic filler and bisphenola-glycidyl dimethacrylate (Bis-GMA)-based resin as an organic matrix. Alumina bead powder was manufactured by fusing crushed β£-alumina powder and quenching it. The beads took a spherical form 3 m in

## Abstract Tensile strength of the interface between hydroxyapatite (HA) and bone was tested. Scanning electron microscopy was used to observe the tensile failure mode and the morphological change of hydroxyapatite ceramic surface in bone. The porosity of hydroxyapatite is 14% and pore size less t
The interface shear strength of uncoated Ti-6A1-4V, dense sintered hydroxyapatite (HA), and HA-coated Ti-6A1-4V were compared. Interface shear strength was determined using a transcortical push-out model in dogs 4 and 12 weeks after implantation. The interface shear strength of dense sintered HA and
